利用修正后的哈密顿量计算非简并拉曼过程中双模光场场熵的演化，并研究了原子能级的交流斯塔克位移对场熵演化和原子-场之间的缠绕的影响.结果显示：交流斯塔克位移的存在使双模光场的熵的演化呈现出较完美的周期性，并且演化的周期以及原子-光场缠绕的程度均受交流斯塔克位移的影响.

Using the modified effective Hamiltonian for non-degenerate Raman process, we have calculated the evolution of the two-mode field entropy and investigated the influence of the AC-Stark shift on the evolution of the field entropy and the atom-field entanglement. It is shown that in the presence of AC-Stark shift, the evolution of the two-mode field entropy has a beautiful periodicity, and the evolution period and the degree of atom-field entanglement are affected by the AC-Stark shift.
